What are the conditions for abnormal noise in the diaphragm coupling?

2022-06-25 08:52

(1) The interval between the two ends of the coupling is too wide, causing the diaphragm to be subjected to a large axial force, and the twisted holes or twisted bolts are worn, resulting in abnormal noise;

(2) The axial offset at both ends of the coupling is too large or the deflection angle is too large, which will also cause vibration and abnormal noise when the equipment is running;

(3) When the speed of the active end and the passive end is different, it will also cause vibration and abnormal noise when the equipment is running;

(4) The speed code disc of the motor is faulty, causing the speed of the motor to be fast and slow, which makes the diaphragm coupling abnormal sound.
